GREENFIELD — Kat Arce of Greenfield nearly missed seeing her own “15 minutes of fame” as a glamorous makeover on the Rachel Ray Show — because of a power-outage at her home just before the television show aired Wednesday at 9 a.m. But Arce, her son, fiance, and two other friends who came over to watch the show piled into cars and headed to Angel Cox’s home, to watch.

When asked what she thought of seeing her new, more-stylish self on TV, Arce said, “It was amusing. I looked as nervous as I thought I would.”

She said that walking onto the stage, with her straighter, darker hair, in a knockout purple dress and high heels — then standing still while the host Rachel Ray conferred with the beauty expert and health expert about Arce’s makeover — was the hardest part. Those few minutes seemed to stretch on and on.

“I don’t think I unclenched my hands the whole time,” she said. “I’ve seen the shows, and I knew I would have to stand. I knew it would be awkward. And it was.”

Arce, 44, works as a dispatcher for an airline shuttle service. Months ago, she wrote to the talk show’s website, saying she needed a new look after being mistaken for being older than her age.

In October, when she was selected for an “age-defying” makeover, Arce and Cox took a two-day, all-expenses-paid trip to New York City, where a beauty consultant helped Arce pick out a new outfit, high-heel ankle-strapped shoes, and where hair- and make-up artists gave her a new look.

Arce said Wednesday morning that many of her family members in Worcester would be seeing her new look for the first time when they watched the program.

The show hosts stressed that looking “older than your years” could make you feel older than you are. One commentator said she hoped the makeover would help Arce “regain her self confidence.”

After seeing the program Arce remarked, “Anybody who knows me would know I don’t lack self-confidence.”
